Acer aspire 5050 W7 with wow 7.0.1

Hello people, i'm triying to activate windows 7 with wow 7.0.1 but i dont have any satisfactory result. I tried before to use another loaders but when i see the letters starting windows it's freeze.

I install wow but it's doesnt work. I follow the steps, extract at the boot drive, install it, write at prompt the commands but all is equal, at least with wow i dont need to reinstall w7.

Anyone have an idea? I tryed to find but you have hundred of post and pages and find something it's really difficult. Oh and you know if it's better to flash the bios for activate it? I search for any bios mod for this computer and i see that one man ask for it but i didn't find the answer.
